ONLINE: The universe is filled with extreme, violent objects. These objects, for millennia hidden from our view, have been revealed by modern telescopes and spacecraft. This course will describe a few of these in four main topic areas. The first lecture will describe various exotic stars, including pulsars and neutron stars, but will show that “normal” stars like our sun also have a hidden, violent nature. Some stars end their lives in massive explosions. These supernova explosions will be covered in lecture two. On a vastly larger scale, galaxies can show extremely violent outbursts originating from massive black holes in the galaxy core. These will be covered in lecture three. The most exotic phenomenon in the universe is the universe itself. Aspects of our expanding universe will be covered in lecture four. The course will give students a clear appreciation of some of the wonders of our universe and how modern science and technology have led to their discoveries. | Lecture + Q&A.
